Hey1, a Mediator of Notch Signaling, Is an Androgen Receptor Corepressor [PDF]

Molecular and Cellular Biology, 2005
Hey1 is a member of the basic helix-loop-helix-Orange family of transcriptional repressors that mediate Notch signaling. Here we show that transcription from androgen-dependent target genes is inhibited by Hey1 and that expression of a constitutively active form of Notch is capable of repressing transactivation by the endogenous androgen receptor (AR).

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

FEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Fungal CSL transcription factors [PDF]

, 2007
Background: The CSL (CBF1/RBP-J kappa/Suppressor of Hairless/LAG-1) transcription factor family members are well-known components of the transmembrane receptor Notch signaling pathway, which plays a critical role in metazoan development. They function as

A role for actomyosin contractility in Notch signaling

BMC Biology, 2019
Background Notch-Delta signaling functions across a wide array of animal systems to break symmetry in a sheet of undifferentiated cells and generate cells with different fates, a process known as lateral inhibition.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Regulation of the self-renewal vs. differentiation decision in the C.elegans germline [PDF]

, 2011
Adult stem cells are the basis of our reproductive potential, of tissue growth and maintenance, and of wound healing and regeneration. Ageing phenotypes such as hair loss or brittle bones in fact reflect the gradual decline of the proliferative ...

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...

iRHOM2 in skin disease and oesophageal cancer [PDF]

, 2015
PhDMutations in RHBDF2, the gene encoding inactive rhomboid protein iRHOM2, result in the dominantly inherited condition Tylosis with oesophageal cancer (TOC). TOC causes plamoplantar keratoderma, oral precursor lesions and up to a 95 % life-time risk of

RETRACTED: Molecular structure and dimeric organization of the Notch extracellular domain as revealed by electron microscopy.

PLoS ONE, 2010
BackgroundThe Notch receptor links cell fate decisions of one cell to that of the immediate cellular neighbor. In humans, malfunction of Notch signaling results in diseases and congenital disorders. Structural information is essential for gaining insight

Structural conservation of Notch receptors and ligands

Seminars in Cell & Developmental Biology, 1998
The Notch signalling pathway is an evolutionarily conserved cell-to-cell communication system utilized multiple times and in many tissues during development. The outcome of an interaction between Notch and its ligands is highly influenced by factors both extrinsic and intrinsic to Notch expressing cells, suggesting that Notch functions either directly ...
